InoZet® Pendulum Bridge

In search of perfect roundness

InoZet® Pendulum Bridge
  • Innovative Clamping Solution 
     

    With InoZet® you can turn your existing 3-jaw chuck into a highly flexible, compensating 6-jaw chuck in no time at all.

    Owing to the variable positioning of the clamping jaws on the pendulum segments you can cover the entire clamping range with one set of standard clamping jaws only for maximum flexibility. 

    You do not need countless pendulum clamping jaws or any special constructions – which leads to enormous cost savings.

    InoZet® offers the following advantages:

    • Your 3-jaw chuck turns into a compensating 6-jaw chuck

    • One set of clamping jaws covers the entire clamping range of the chuck

    • For internal and external clamping

    • Ideal for processing deformation-sensitive components as well as out-of-round blanks and components deformed by thermal treatment
    • Can be retrofitted for all chuck sizes from diameters of 210 mm
    • The pendulum mechanism is protected from soiling
    • Huge cost savings by dispensing with expensive special clamping jaws
    • Ideal true running properties

    Areas of Application

    • Deformation-sensitive raw parts
    • Out-of-round parts
    • Parts that are deformed after thermal treatment

InoTop® - Hybrid Clamping Jaw

The innovative InoTop® hybrid clamping jaw sets new standards in the turning technology

  • InoTop®-hybrid-clamping-jaw was specially designed for deformation-sensitive workpieces in turning applications. Fitted on an standard 3-jaw chuck, deformation-sensitive workpieces are being centred from the outside and and clamped from the inside without any pressure. Thus InoTop® avoids the unwanted forming of polygon

     

    Optimal Roundness Due to Counter Bearings

    INOTop® produces best roundness results thanks to the
    fixed counter bearing principle. By using InoTop® , thin-walled
    parts in particular can be clamped without polygon formation.

    • Part is centered without pressure from outside for clamping
    • Perfect roundness results
    • Defined clamping force by the moveable jaw
    • No expensive special clamping solutions needed

InoTop® - Hybrid Clamping Jaw
